Apparatus and method for controlling turn signal

摘要

An apparatus for controlling a turn signal includes a turn signal switch configured to include at least one of operation modes of a lane change mode and a turn mode. A steering angle sensor is configured to detect a steering angle of a vehicle. A controller is configured to control the turn signal switch to turn on and off a turn signal lamp according to an operation mode and to turn off the turn signal lamp in at least one of a case in which the steering angle, which returns in a reverse direction to a course change direction detected by the steering angle sensor, reaches a preset angle and a case in which an operation time of the turn signal switch exceeds a preset time.

1. An apparatus for controlling a turn signal, comprising:
a turn signal switch configured to include at least one of operation modes of a lane change mode and a turn mode; a steering angle sensor configured to detect a steering angle of a vehicle; and a controller configured to control the turn signal switch to turn on and off a turn signal lamp depending on an operation mode and to turn off the turn signal lamp in at least one of a case in which the steering angle, which returns in a reverse direction to a course change direction detected by the steering angle sensor, reaches a preset angle and a case in which an operation time of the turn signal switch exceeds a preset time, wherein the controller determines the operation mode based on contact signals generated when the turn signal switch passes through a plurality of contacts, wherein the controller determines the operation mode as any one of the lane change mode and the turn mode depending on a rising edge generated when the contact signal is not inputted initially and is then inputted and a falling edge generated when the contact signal is inputted initially and is then not inputted and a number of edges of the contact signals, and wherein the contact signal is not inputted from a middle contact among the plurality of the contacts.
